Specification of Letters Patent.

Patented Apr. 16, 1918.

Application filed September 15, 1916'. Serial No. 120,272.

To all whom t may concern.'

Be it known that I, DENNIS C. CHARMOIS, a citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Waste-Traps, of which the following is a specification.

The invention relates to waste traps for bathk tubs and the like, and the objects of the improvement include the formation of the trap with a minimum depth and length, which can be positioned to discharge in any lateral direction from the Waste pipe of the tub, and will have an accessible clean-out opening above the water seal in any such position. A further feature of the invention relates to the use ofa cover plate which is normally secured to conceal the entire head of the trap and may be swung from normal position to uncover the clean-out opening without disturbing or disconnecting the waste pipe. v

These objects of the invention and ancillary advantages are attained by the construction and arrangement of a preferred embodiment of the invention illustrated in the accompanying drawing forming part hereof, in which Figure l is a fragmentary side elevation i of a bath tub waste pipe showing the floor, the waste trap and the waste pipe in longitudinal section;

Fig. 2, an enlarged plan view of the waste trap and a portion of the drain pipe; and

1Fig. 3, a detached plan view of the cover ate. p Similar numerals refer to similar parts throughout the drawings.

The tubular body portion 1 of the waste trap is curved in the usual U-shaped form and the discharge side or end 2 thereof is abruptly bent or curved laterally outward, for connection with or attachment to the discharge pipe 3, which connection or attachment may be made by an ordinary solderedvjoint 4:.

The receiving side or end 5 of the trap is curved or deflected inward over the U- shaped body portion thereof, and the inner wall 6 of this portion is curved or inclined more rapidly than the outer wall 7 thereof, thus forming a hopper which is closed by the preferably integral oval shaped head plate 8; the parts being preferably so proportioned and arranged that the center of the head will be positioned directly over the center oraxis of the U-shaped body portion 1 of the trap and above the plane of the discharge pipe. i

Two like openings 9 and 9a are provided in the oval headv of the trap and are pre erably y centrally located, one in each end portion thereof, as shown in Figs. 1 and 2.

These openings are preferably provided with screw threads and are adapted to receive either the waste pipe 10 leading from the bath tub l1 or the screw plug 12 which is employed to normally close the opening which is used for inserting a clean-out tool. For the purpose lof thus connecting the waste pipe to the head, the lower endthereof is preferably provided with a threaded bushing 10a, secured thereto as by means of v solder, and adapted to fit into the openings. The head 8 is also preferably provided with laterally'protruding ears 13 on each side which are adapted to rest upon the floor 14- for supporting the trap therefrom. The cover plate 15 is made oval shaped somewhat larger n length and width than the head of the trap, and is preferably .provided with the belleshaped rim 16 which is adapted to rest upon the floor around the trap head while the body portion of the plate is arched over thehead yand the screw. plug which protrudes 'upward therefrom. The larger aperture 17 is centrally provided in one end of the cover plate and is adapted to neatly lit around the waste pipe 10 of the bath tub; and the similar aperture 18 is centrally provided in the other end of the cover plate, and is adapted to fit neatly around the shank 19 of the cap screw 20, by means of which the coverv plate is secured to the screw plug 12.

By this construction and arrangement, it is evident that by removing the cap screw 20, and slightly raising the cover plate, the same can be rotated around the waste pipe 10 as a pivot into the position shown by broken lines in Fig. l, whereupon the screw plug can be removed and a suitable tool, nozzle or hose may be entered through the opening 9 or 9a thus exposed for cleaning out the trap.

It is also evident that when the discharge pipe 3 leads away from the rear end of the tub 11 and the waste pipe 10 of the tub is entered in the outer opening 9 in the head of the trap, the inner opening 9a thereof is located in an unobstructed position in rear of said waste pipe; but if the discharge pipe 3 leads forward under the bath tub, the waste pipe thereof can be entered into the inner opening 9a of the trap thus leaving the outer opening 9 thereof freely exposed and aecessible in rear of said waste pipe, which relation of the tub and waste pipe is shown by broken lines in Fig. l.

It is furthermore evident that by curving inward the receiving end of the trap so that its head will be located directly over the U-shaped body portion thereof, and above the plane of the discharge pipe, the length of the trap will be reduced to a minimum thus facilitating its location in constricted places.

And it is finally evident that by elongating the receiving end or hopper of the trap underneath its head, there is formed a suitable chamber through which a tool or hose can be entered from either one of the openings in the head and thence deflected through and around the U-shaped body portion of the trap for cleaning the same in the usual manner.

I claim:

l. Awaste trap having a tubular U-shaped body portion with a discharge pipe leading laterally from one `end thereof, a hopper on the kother end having its mouth directly over the body portion above the plane of the discharge pipe, Vand a closure for the mouth having waste-pipe and clean-out openings therein. v

2. Awaste trap having a tubular U-shaped body portion with a discharge pipe leading laterally from one end and a receiving hopper formed on the other end having a head plate closing the same, centrally located directly above the U-shaped body portion and above the plane of the discharge pipe, there being like openings in the head plate, each of said openings being adapted to receive either a waste pipe or a screw plug.

3. A waste trap having a tubular U-shaped body portion with a discharge pipe leading laterally from one end and the walls of the other end inclined inward to form a receiving hopper having an oval head plate centrally located directly above the U-shaped body portion and above the plane of the discharge pipe, there being like openings in the ends of the head plate, each of which openings are adapted to receive either a waste pipe or a screw plug.

4:. A waste trap having an elongated head plate thereon with like openings in the ends thereof, a waste pipe in one opening and a screw plug in the other opening, and an elongated cover plate having an aperture in one end fitting around the drain pipe and means at the other end for normally securing the plate in position over the head.

5. A waste trap having an elongated head plate thereon with like openings in the ends thereof, a waste pipe in one opening and a screw plug in the other opening, an elongated cover plate having two openings therein, one opening fitting around the waste pipe, and a screw extending through the other opening into the screw plug.

6. A waste trap having an elongated headplate thereon, with openings in the ends thereof, a waste pipe in one opening and a screw plug in the other opening, and an elongated cover plate for the head plate having an aperture therein tting around the drain pipe.
